The Efficacy of Graphene Foams for Culturing Mesenchymal Stem Cells and Their Differentiation into Dopaminergic Neurons

Figure 7

Comparison of differentiated DA neurons with mouse MSCs in contact with (a, c, e) collagen gels and in contact with (b, d, f) collagen-coated GF. Confirmation of differentiation of mouse mesenchymal stem cells (MSCs) into a neuronal phenotype resembling DA neurons was exhibited in all cases, but cells differentiated in graphene foam-based scaffolds exhibited significantly longer neurite extensions than those cultured in contact with collagen. Scale bar is 30 μm in all images.
